Comment: We would like a 3 ft tall concrete planter around our backyard. Part of it would need to double as a retaining wall as well. We would also like 2 concrete posts on each side of the house for our gates to be installed on. The measurements for the planter are roughly 106ft across the back x 54ft on one side 23ft on the other. We were also thinking of having a couple concrete benches built into it. Thank you, we look forward to hearing back from you.
